Application filed August 21, 1911. Serial No; 645,235.

To all whom it may concern:

Be it known that I, OLOF EMANUEL MYREN JoI-iNsoN, a citizen of Sweden,residing at Newett, in the county of Chafi'ee and State of Colorado,have invented certain new and useful Improvements in Hatchets, of whichthe following is a specification.

This invention relates to improvements in hatchets and its object is toproduce a tool of this class having a detachable blade secured to thehead so that should the blade be broken or damaged in usage it may bereplaced with a new one without destroying the utility of the tool.

Other objects are to produce a tool of this character that, is simpleand inexpensive to manufacture, efficient and durable.

With the foregoing and other objects in view the invention consists inthe combination and arrangement of parts to be hereinafter more fullydescribed in the following specification, pointed out in the claim andillustrated in the accompanying drawing which forms a part of the saidspecification and in which- Figure 1 is a side elevation of the toolshowing the handle partly broken away and the blade retaining mechanismin dotted lines. Fig. 2 is an elevation of the head of the tool, partlyin section, showing the blade retaining mechanism. Fig. 3 is an endview. gig. 4 is an inverted plan of a portion of Like referencecharacters indicate corresponding parts throughout the several views.

1 is the hatchet handle of ordinary construction and provided with ahead 2 formed without the usual integral cutting blade but with meansfor retaining my removable blade. At the forward end of the head 2 itssolid body portion is terminated at 6 but the lateral walls areprojected beyondthis line and turned inwardly toward each other to formoppositely disposed dovetails,

3 and 4 and a space is formed between the said dovetails and between theline 6 and the dovetails. The latter cavity is termi-. nated by ashoulder 7 which is projected from the head 2 to meet the dovetailcontinuations at 5 which latter members extend from the upper to thelower edge of the head 2 or its entire depth.

8 is the detachable blade having a cutting edge 9 and a neck 10projected beyond its rear termination and ending in a head 11. Withinthis head is formed a rectangular recess 12 in which is secured a lever13, by

a pivot 14 fastened in the head 11, having its upper end beveled asshown.

15 is a spring secured in the recessed head 11 having its opposite endfixed in a recess 16 in the lever 13 for the purpose of drawing thelever toward the said head. A lug 17 secured to the lever 13 is adaptedto enter a recess 18 in the head 2. Lying loosely within the recess 12of the head 11 is a beveled block 19 whose bevel normally engages thebeveled surface of the lever 13 and the upper end of which is engagedbya screw 20 entering an aperture 21 in the up- I per edge of the blade.

To attach the removable blade to the head 2 the neck 11 is placedbetween the dovetails 3 and 4t and the head 11 inserted in the cavitybetween the dovetails and the hatchethead 2 until the lower end of thehead 11 abuts the shoulder 7 as shown in Figs. 1 and 2. The screw 20 isnow driven down entirely into the aperture 21 when it will engage theblock 19 and force the same against the lever 13 thus driving the latteragainst the tension of the spring 15 upon the head 2 causing the lug 17to enter the recess 18 of the said head when the blade will be inoperative position. The dovetails 3 and 4 prevent the blade from leavingits position in a forward direction, the lug l7 prevents an upwardmovement and the shoulder 7 prevents a downward movement of the saidblade.

What I claim is Ahatchet comprising a handle, a head secured to saidhandle and formed with a forwardly projected shoulder at its lowertermination and with a lug receiving recess, oppositely disposeddovetailsprojected from the upper termination of the said head andprolonged its entire depth to abut the said shoulder, a detachable bladeformed with a neck for insertion betweenthe said dovetails, ahead formedwith a suitable-recess a lug-carriedhy said lever for insertion 111 therecess in the hatchet-head, a beveled block m y engaging h s d le e andaiscrew for engagement With the said 'beV- eled block. I v

In testimony that I claim the foregoing 10 as my own I have heretoaffixed my signature in the presence of two subscribing Witness sit v a01m EMANUEL MYREN JOHNSON.
